Abstract
A sectional door installation comprises a series of horizontal door panels mounted on opposite ends on scissors linkages to move between a deployed generally vertical position closing the doorway to a withdrawn position wherein the panels are arranged generally horizontally at the upper end of the doorway. The panels are transparent and are detachably connected to the scissors mechanism at their opposite ends so that they can readily disengage therefrom when impacted by an object such as an automobile, without damaging the object or themselves being damaged.
